获取状态栏的高度。

 1     private static int statusBarHeight;
 2     
 3     private int getStatusBarHeight() {
 4         if (statusBarHeight == 0) {
 5             try {
 6                 Class<?> c = Class.forName("com.android.internal.R$dimen");
 7                 Object o = c.newInstance();
 8                 Field field = c.getField("status_bar_height");
 9                 int x = (Integer) field.get(o);
10                 statusBarHeight = getResources().getDimensionPixelSize(x);
11             } catch (Exception e) {
12                 e.printStackTrace();
13             }
14         }
15         return statusBarHeight;
16     }

获取屏幕的宽和高

方法一：

1         WindowManager mWm = (WindowManager) getSystemService(WINDOW_SERVICE);
2         int screenWidth = mWm.getDefaultDisplay().getWidth();
3         int screenHeight = mWm.getDefaultDisplay().getHeight();

注意：getWidth()和getHeight()方法已经过时

方法二：

1         WindowManager mWm = (WindowManager) getSystemService(WINDOW_SERVICE);    
2         Point point= new Point();
3         mWm.getDefaultDisplay().getRealSize(point);
4         int screenWidth=point.x;
5         int screenHeight=point.y;
